Every time I start my car, I see white smoke come out of my tailpipes and i mean a lot of smoke but it's only when i start it. While I'm driving it, i smell carbon monoxide the whole time. What could be the problem?

 

White smoke indicates coolant/water. Check for any coolant leaks, do a pressure test. Carbon monoxide is odorless, you cant smell it. You could be smelling gas, but that typically is black smoke. If you're smelling exhaust while you're driving, check for exhaust leaks around the engine, like the manifold gasket or y-pipe.

 

The white (slightly blue) smoke is most likely valve seals. Heavy exhaust smell could be from a leak, or a gutted out or missing cat.

 

Put a cat on it and the smell will go away
